High-Resolution Three-Dimensional NMR Structure Of The KRAS Proto-Oncogene Promoter Reveals Key Features Of A G-Quadruplex Involved In Transcriptional Regulation [PDF]

, 2017
Non-canonical base pairing within guanine-rich DNA and RNA sequences can produce G-quartets, whose stacking leads to the formation of a G-quadruplex (G4).

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Sequential induction of NF-κB/Rel family proteins during B-cell terminal differentiation [PDF]

, 1994
The NF-kappa B/Rel family of at least five transcription factor polypeptides is thought to function both as a developmental regulator in B cells and as a rapid response system in all cells. To examine this notion in more detail, we determined the protein

Disrupting the Formation of YAP Condensates Promotes the Activation of AMPKα to Inhibit the Progression of Primary Liver Cancer

Advanced Science, EarlyView.
This study systematically investigates the function and molecular mechanisms of YAP phase separation in multiple primary liver cancers. These findings provide novel insights into phase separation‐mediated primary liver cancer development and validate targeted disruption of this process as an effective therapeutic strategy for primary liver cancer ...

A20 Facilitates Oxaliplatin Sensitivity in Colorectal Cancer Through Monoubiquitylation of IKK‐β

Advanced Science, EarlyView.
This study demonstrates that the expression of A20, a ubiquitin‐editing enzyme, is positively correlated with oxaliplatin sensitivity in colorectal cancer (CRC). Mechanistically, A20 enhances oxaliplatin sensitivity by inhibiting NF‐κB nuclear translocation through monoubiquitination of IKK‐β.

The RNA-binding protein LARP1 is a post-transcriptional regulator of survival and tumorigenesis in ovarian cancer [PDF]

, 2015
RNA-binding proteins (RBPs) are increasingly identified as post-transcriptional drivers of cancer progression. The RBP LARP1 is an mRNA stability regulator, and elevated expression of the protein in hepatocellular and lung cancers is correlated with ...

SIRT5–RAC2 Axis Drives Monocyte‐to‐Macrophage Differentiation to Promote Inflammatory Injury in Premature Ovarian Insufficiency

Advanced Science, EarlyView.
SIRT5 desuccinylates and stabilizes RAC2, activating CSF1R‐dependent signaling to drive monocyte differentiation into M0 macrophages and their polarization toward pro‐inflammatory M1 phenotypes in CTX‐induced premature ovarian insufficiency. Inhibiting the SIRT5‐RAC2 axis attenuates inflammation, reduces granulosa cell apoptosis, and preserves ...

Antiapoptotic herpesvirus Bcl-2 homologs escape caspase-mediated conversion to proapoptotic proteins [PDF]

, 2000
The antiapoptotic Bcl-2 and Bcl-x(L) proteins of mammals are converted into potent proapoptotic factors when they are cleaved by caspases, a family of apoptosis-inducing proteases (E. H.-Y. Cheng, D. G. Kirsch, R. J. Clem, R. Ravi, M. B. Kastan, A. Bedi,

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...
